Google will kill off Inbox by March 2019, so time to move on if you liked it.

Much easier for me to just receive every email chronologically in the regular Gmail.https://venturebeat.com/2018/09/12/g...in-march-2019/

One thing I do find attractive about open source software running on some Linux distro is that they seem to rarely die off completely, and even when they do aren't usually shut down all at once. Someone always seems to have another version somewhere, or takes over and maintains the thing. It only requires a few passionate people to keep some software going.
